研究概览
简要总结
RSC-101 is a Phase 1a/1b clinical trial of RSC-1255 in adult study participants with advanced solid tumor malignancies who are intolerant of existing therapies known to provide clinical benefit, have disease that has progressed after standard therapy, or have previously failed other therapies. The study has two phases. The purpose of Phase 1a (Dose Escalation) is to confirm the appropriate treatment dose and Phase 1b (Dose Expansion) is to characterize the safety and efficacy of RSC-1255.
详细描述
RSC-1255 is an orally bioavailable, small-molecule direct pan-mutant and wild-type RAS inhibitor. RSC-101 is a Phase 1a/1b, open-label, multi-center, non-randomized, Dose Escalation and Dose Expansion study in participants with advanced solid tumor malignancies. Study enrollment is approximately 134 participants. All participants receive oral RSC-1255, twice daily as monotherapy. Following Phase 1a (Dose Escalation) to identify the Maximum Tolerated Dose and Recommended Dose for use in Phase 1b, additional participants are enrolled in the Phase 1b (Dose Expansion) to further characterize the safety, pharmacology, and the clinical efficacy of RSC-1255 as monotherapy and in combination with the autophagy inhibitor hydroxychloroquine (HCQ).

结局指标
主要结局
Maximum Tolerated Dose (MTD) for RSC-1255 as monotherapy
时间窗: Approximately 30 months
The number and type of dose-limiting toxicities (DLTs) as defined in the protocol that occur during the first 21 days of treatment and maximum grade of all treatment-related events using CTCAE V5.0 will be used to identify a safe and tolerable dose.
Recommended Phase 2 Dose (RP2D) for RSC-1255 as monotherapy
时间窗: Approximately 12 months
The number and type of DLTs as defined in the protocol that occur during the first 21 days of treatment and maximum grade of all treatment-related adverse events using CTCAE 5.0 will be used to identify a safe and tolerable dose.
